The
drawing on the sign shows the functioning of the mosaic, the hypocaust
system for the baths and the hot room.

The
text in English reads: The public baths - Very close to the forum, and dating
probably from the beginning of our era, were the public baths, or therms.
Excavations have revealed the room for hot baths, caldarium, that
for cold baths, frigidarium, and the tepidarium, which served
as a transition between the two, and possessed a floor decorated with a
geometrically patterned mosaic that is now in the museum. The therms were
indispensable for the social life of every Roman and Romanised city, where
they offered relaxation, a meeting place, and bodily care. Frequented equally
by both sexes, the establishments were either separate, or observed different
entry hours.
